A stretched wire of length 1 m and weighing 1 gram is in unison with a tuning fork of frequency 200 Hz. The tension in the wire will be

A

160 N

B

80 N

C

320 N

D

200 N

Text Solution

Verified by Experts

The correct Answer is:
A
`n = 1/(2L) sqrt(T//m)" "m = 10^(-3)//1`
` :. T = 4n^(2)L^(2) m = 4 xx 200 xx 200 xx 1^(2) xx 10^(-3) xx 10^(-3) = 160 N`
